Abstract
A printed circuit board comprises a base material containing at least one conductor path and at least one heat-conducting path forming a heating layer embedded in the base material for generating and conducting heat. The circuit board is characterized in that the heat-conducting path comprises a PTC thermistor with a constant voltage applied thereto. The invention further relates to a plug-in module comprising such a circuit board, and additionally to a field device comprising such a circuit board and/or such a plug-in module.
